Grimling Forest Camp #2 to North eventFollow

Anyone know if the Grimling Forest Camp #2 event is broken? The Camp #2 to the North, where there are corpsesummoners that summon 3-4 mobs into the center pit. Dialog says to leave them alone, so I've tried not killing any of them, and killing all the summoned mobs, neither works. Any ideas on this would be greatly appreciated, as I've almsot done all 8 others, maybe have at one time or another, but never have been able to finish this one.

Yther Ore.
